'Nazirite' in the Bible

“Say to the sons of Israel, ‘When a man or a woman makes a special vow, the vow of a Nazirite, that is, one separated and dedicated to the Lord,

‘Now this is the law of the Nazirite when the days of his separation and dedication are fulfilled: he shall bring the offering to the doorway of the Tent of Meeting (tabernacle).

The Nazirite shall shave his dedicated head at the doorway of the Tent of Meeting (tabernacle), and take the dedicated hair of his head and put it on the fire which is under the sacrifice of the peace offerings.

The priest shall take the boiled shoulder of the ram, and one unleavened [ring-shaped] loaf out of the basket, and one unleavened flat cake and shall put them on the hands of the Nazirite after he has shaved his dedicated hair.

Then the priest shall wave them as a wave offering before the Lord; they are a holy portion for the priest, together with the breast that is waved and the thigh that is offered by lifting up; and afterward the Nazirite may drink wine.’

“This is the law for the Nazirite who vows his offering to the Lord for his separation, besides what else he is able to afford, according to the vow which he has vowed; so shall he do according to the law for his separation and abstinence [as a Nazirite].”

For behold, you shall conceive and give birth to a son. No razor shall come upon his head, for the boy shall be a Nazirite [dedicated] to God from birth; and he shall begin to rescue Israel from the hands of the Philistines.”

But He said to me, ‘Behold, you shall conceive and give birth to a son, and now you shall not drink wine or [any other] intoxicating drink, nor eat anything [ceremonially] unclean, for the boy shall be a Nazirite to God from birth to the day of his death.’”

Then [finally] he told her everything that was in his heart and said to her, “A razor has never been used on my head, for I have been a Nazirite to God from my mother’s womb. If I am shaved, then my strength will leave me, and I will become weak and be like any [other] man.”
